摘要
通过对河南省鹿邑县近5年来气象条件统计与形成棉花产量和品质的诸多要素间的相关分析,发现影响本地棉花优质高产的主要气象因素是温度、光照和降水。为充分利用气候资源,提高棉花产量和品质,应选用中熟品种,适时采取双膜营养钵育苗;实施地膜覆盖,改善田间小气候;采用全程化调,控制棉花长势。
Through the correlation analysis of meteorological factors and yield-quality based on the observation during the past 5 years in Luyi, result shows that the key factors of effecting High-quality high-yield cotton are temperature, sunlight and precipitation. In order to make full use of climate resources and improve the yield and quality, medium-maturing cotton should be chosen and double covering nutrition trough should be adopted in proper time. Field covering can improve the micro-clime and adjustment of hormone in whole growth period can control the growing.
